4.1 DK12-11-IO – Use and application
The DK12 contrast sensor with IO-Link interface enables consistent communication for
diagnosing and parameterizing through to the sensor level for the first time and makes
the intelligence already integrated in every DK12 contrast sensor fully available to the user.
This provides particular advantages in the service area (fault elimination, maintenance and
device replacement), during commissioning (cloning, identification, configuration and
localization) and during operation (job changeover, continuous parameter monitoring and
online diagnosis).
What is IO-Link?
IO-Link is a new dimension of communication of and with sensors. The possibility of making the
intelligence that is already integrated in every sensor fully available to the user opens up new
routes for automation. The use of IO-Link produces positive effects for all fields of application in
factory automation. This includes everything from planning and commissioning, to flexible
operation and service. The reduction of the diversity of interfaces alone, which is, for example,
a result of analog sensor inputs and the complex installation required, offers the user a high
savings potential.
Typical areas of application for the DK12-11-IO include
• Printing and paper industry
• Packaging industry

Operation
7.1 Operation Without IO-Link
The sensor is operated without an IO-Link using the rotary switch on top of the sensor. In
illustration under point 3.
1. Operating indicator
2. Signal indicator
3. Teach-In switch
You have the option of selecting one of 4 switch settings.
• Position S - Switching mode
• Position TM - Teach-in mark
• Position TB - Teach-in background
• Position TD - Dynamic teach-in
When changing the position of the rotary switch, remember that you must adhere to a time lock
of approximately 2 seconds. This means that the rotary switch must remain in a new position
constantly for 2 seconds so that the sensor accepts the selected mode, which is indicated by a
change in the flashing function of the display LEDs.
Static Teach-In
The mark or the background can be taught-in in static Teach-In mode either together or
separately. The order is not relevant here. Therefore, it is not mandatory to always teach-in
the mark and the background.
Teaching in the Mark
1. Position the object that you wish to teach in as a mark in front of the sensor at the specified
distance.
2. Set the rotary switch to TM position (teach-in mark).
3. The mark is detected when the rotary switch remains in the TM position constantly for 2
seconds.
4. The green and yellow display LEDs flash simultaneously after teach-in has been
completed (f=2.5 Hz).
You have taught in the mark.
To complete the teach-in process, turn the rotary switch to the S position (see Switching
mode).

Teaching in the Background
1. Position the object that you wish to teach in as a background in front of the sensor at the
specified distance.
2. Set the rotary switch to TB position (teach-in background).
3. The background is taught in when the rotary switch remains in the TB position constantly
for 2 seconds.
4. The green and yellow display LEDs flash alternately after teach-in has been completed
(f=2.5 Hz).
You have taught in the background.
To complete the teach-in process, turn the rotary switch to the S position (see Switching
mode).
Dynamic Teach-In
The dynamic teach-in operation begins when the rotary switch remains in the TD position
constantly for 2 seconds. Values are then transferred continually. The first signals received
after changing to "Dynamic Teach-In" mode are interpreted by the sensor as a background.
The largest deviation from the background during the entire "Teach-In Dynamic" mode is
interpreted as a mark. The green and yellow LED indicators flash simultaneously at a
frequency of 1 Hz during this mode.
1. Position the object that you wish to teach in as a background in front of the sensor at the
specified distance.
2. Turn the rotary switch to the TD position. Both LEDs then flash simultaneously at a
frequency of 1 Hz in the subsequent process.
3. Wait approx. 4 seconds.
4. Now slide the object that you wish to teach in as a mark past the sensor at the specified
distance.
You have taught in the values for the background and mark.
To complete the teach-in process, turn the rotary switch to the S position (see Switching
mode).
Switching Mode
The rotary switch is located in the S position. The teach-in procedure has finished. The
received signals of all 3 transmitter light colors for the mark and background are evaluated.
1. The mark and background were taught-in successfully and the sensor changes to switching
mode.
The most favorable transmitter light color for the taught-in contrast is selected. At this
point, the values are adopted permanently and used as operating parameters. The
switching threshold is set midway between the mark and the background. The outputs Q1
and Q2 are active and indicate the current signal state (mark or background detected).
The output Q2 always generates an output signal that is inverted to output Q1.
2. The mark and background were taught in unsuccessfully. The sensor indicates a fault via
the LED indicators (the yellow and green LEDs flash quickly and alternately).
The taught-in contrast is too low for all 3 transmitter light colors. The sensor automatically
changes to switching mode and the last valid values for the mark and background are
adopted. The recently measured values for the mark and background are discarded. The
yellow and green display LEDs flash alternately at a frequency of 8 Hz for approx. 7
seconds.

DK12-11-IO
Operation
7.2 Operation with IO-Link
The sensor parameters are different for each device. These parameters are described in a
standardized format in the device description IODD (IO Device Description). The IODD can be
imported into various engineering tools from different system providers, providing they support
IODD. The sensor can then be parameterized and diagnosed using the relevant tool and a user
interface generated from the IODD. Flow diagrams in the appendix explain the principle
sequence of the parameter exchange in different operating situations see chapter 9.1.
7.3 Operation via DTM
You also have the option of operating the sensor using an FDT base application (FDT = Field
Device Tool) and the DTM (Device Type Manger) provided for the sensor. Unlike operation via
the IODD, this method provides extended functions and ensures improved visualization and
convenient operation. The following section describes connection via a FDT base application.
Minimum requirements for operation include the installation of a DTM for the IO-Link master
being used.
